205U/CA low-flow multi-channel pumps • • Flow rates from 0.6 microlitres to 22ml/min per channel Eight planetary-driven stainless-steel rollers give extended tube life 180 :1 speed control range and 19 tube sizes give 36,000 :1 control range High precision, near-pulseless flow through 4 to 32 channels Manual control or analogue auto-control (up to 30V or 32mA) Change cassettes without stopping the pump or disturbing other channels The 200 series provides high-precision pulsation-free pumping. Flow control for each individual channel is provided by multi-turn "click-stop" pressure adjustment...

Tube selection guide Choosing the best tube Watson-Marlow tubing is available in seven materials and over forty sizes, giving an extraordinary range of chemical and application capability. Watson-Marlow pumps are designed for Watson-Marlow tubing tolerances and performance, and no other tubing will provide comparable results. The tubing largely dictates pump performance: Its restitution creates suction, its strength resists pressure, its flex resistance determines pumping life, its bore defines the flow rate, and its wall thickness controls pumping efficiency. Marprene is Watson-Marlow's...

Sta-Pure has a unique composite construction of silicone in a PTFE lattice giving it superior burst resistance up to 7 bar (100psi) and 18 times longer life than silicone tubing. It produces virtually no spalling, is USP Class VI approved and is classified as non toxic. Working temperature range 0C to 80C. Opaque white. Autoclavable, SIP and CIP compatible. Chem-Sure is effectively pumpable PTFE - a high performance composite of PTFE and a high-grade fluoroelastomer - offering extraordinary chemical resistance, long life and very high burst pressures. Chem-Sure is USP Class VI and food...

Physical compatibility Temperature The chart shows the temperature range of each tubing type when suction and delivery pressures are negligible. Operating temperatures of Bioprene, Marprene, Chem-Sure, Sta-Pure and silicone tubing are limited to 80C, but all may be autoclaved up to 135C. -4F Marprene/Bioprene Silicone Neoprene Chem-Sure PVC Sta-Pure Pressure Choose the smallest bore size of tubing which will give the required flow rate. Marprene/Bioprene Silicone Neoprene Chem-Sure PVC Sta-Pure Low Pressure capability Suction As with pressure, choose the smallest bore of tube which will...

Ultra-compact scientific pumps for low flow single or multi-channel applications. The flow rate of all peristaltic pump tubing will reduce over time, with the majority of the change occurring in the first hours and days of use, after which the flow rate will stabilise. Maximum accuracy of metering and...
